BUTLER ON BUTTERFLIES [Mar. 21, astrigera, Scolitantides crawshayi, Pyrgus machacosa, as well as the females of Everes Jcedonga (the male of which was described last year by Mr. Grose-Smith) and of Phrissura nyasana, the male of which I described and figured in these ' Proceedings ' for 1896. Other species of especial interest are Castalius gregorii, Scolitantides stellata (which we previously only possessed from Nyasaland), Chrysophanus abbotti, Stugeta bowlceri, Teracolus celimene, Synchloe glauconome (previously only received from near Aden), Abantis paradisea, and a curious form of Kedestes wallengreni. Writing from Ngong (or Ngongo), Masailand, on September 6th, respecting the first of his consignments, Mr. Crawshay says :- " It is almost two months since I sent m y collection of Butterflies and Moths, which by now I hope will have reached you. In the meantime I have never had a chance of writing to you ; I have been on the move incessantly ever since. " The very day I consigned the box of insects to the Parcel Post I received orders to proceed hither : right glad w as I, too, to get the chance of seeing something of Masailand. * * * * "Having collected some 300 odd Butterflies and Moths, tbe latter being by far the most numerous, I thought I had better send you these by way of a first instalment. All these insects were taken, as you will see from the envelopes, either at, or in the vicinity of Machako's Station-which is the headquarters of what has been delineated as the Ukamba Province, though it also includes the much more important and interesting highlands of Kikuyu (the home of the Wakikuyu, who are strong men) and a portion of Masailand. " The altitude of Machako's is about 5400 feet. It is open plain-laud, not even well watered; but there are hills in the immediate neighbourhood, such as Makimwi and Mowa, partially timbered, partially open down-land, nearly 10U0 feet higher, where I took practically all the most interesting Butterflies, and many of the day-flying Moths, such as the ' Bee' and 'Humming- Bird Hawks.' " It is not a rich Butterfly country I could see at once; it is, however, a rich field for Moths ; those I took in m y tent at night alone gave me plenty to do to put them up : had I ' sugared' I should have secured a great many more. " The rainy seasons of Ukamba are on from about the beginning of March until the end of May, and again from about the middle of October until the end of December; this last rainy season there was very little rain indeed. " Since I left Machako's I have been steadily collecting all the time, except when on the Kegujo expedition, when I never ceased regretting not having brought my net, as there are some lovely and, to me, quite new Butterflies in the forests of Kikuyu; but, of course, we had sterner work in hand there."
